Unfortunately this is not a simple problem. We’re currently using a ShaderEffectSource item to capture the contents of a webview and display a paused thumbnail. This works well while the webview is live and has been shown at least once. But when the app is restored after being killed, only the current webview has been shown, all the other webviews are hidden, so there is no capture available.
QML doesn’t expose any built-in way of persisting the contents of an item as an image on disk, which is what would be needed to restore tab previews. Also note that we’re currently not persisting favicons on disk either, they are being re-downloaded everytime, this is bug #1340585. ** Changed in: webbrowser-app Status: New => Confirmed ** Changed in: webbrowser-app (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1357464 Title: restoring browser shows blank tab previews To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-ux/+bug/1357464/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
